Investopedia explains ‘Self-insure’

Just another short explanation on Self-Insuring to help understand what is going to happen,

Self-insuring against certain losses may be more economical than buying insurance from a third party. The more predictable and smaller the loss is, the more likely the risk is to be retained by a self-insured person. The idea is that since the insurance company aims to make a profit by charging premiums in excess of expected losses, a self insured person should be able to save money by simply setting aside the money that would have been paid as insurance premiums.
